Medium-range 7" quad

First medium/long-range rig! It's definitely a tight build on this frame dubbed "DiveX" by fpvframe.ch. The frame is a 7" true X with a bunch of 3D parts for GoPro, GPS, vTX antenna, Crossfire antenna, etc. Still rocking the Hobbywing combo like in all my other builds. Still on the Runcam Sparrow because I have 16/9 goggles and the Eagle 2 (Pro) has more latency. I did some waterproofing (snowproofing) on this quad, using "Liquid tape" or "Plastidip".

Weight with everything but the battery is 443g (including GoPro and props). AUW is 711/727g on 5S 1800/2200mAh. The 1800mAh is from Swaytronic, the 2200 from mylipo.de

With a conservative end voltage, I get about 8min flight time on the 1800mAh 5s battery (hybrid cruising / freestyle), and it seems I could get about 11-12min from the 2200mAh if I extrapolate my last flight.

EDIT: I changed the TPU mount at the back to house the GPS module and Crossfire antennas in a vertical orientation + I added LEDs.

EDIT 2: I switched to Hobbywing motors for more kV and better 6" compatibility

Hey Charles thanks! Yeah the base design of these parts was done by the frame designer but I made my own version to add the immortal T and GPS (which were not included in the initial vTX antenna mount). In the end and after some testing, I placed the immortal T horizontal at the top of the GoPro mount because it gave me better reception, the vertical mounting shown in the pictures is too close to the frame and stack.

Yes, but I only had 4s 1500mAh batteries. I get about 5-6min out of them, probably more if I cruise. I just got my 5s 1800mAh and 2200mAh batteries this week so I'll do some more tests tomorrow if the weather allows :)

Yeah they are mid-high end regarding price, somewhere in the range of the Brotherhobby Returner R5 or so. Still, they are meant for long-range flying which is usually less risky than freestyle or racing

True. Okay, thank you. Is there any reason I shouldn't go with the runcam Split 2 instead of a 300$ gopro with a long range build? The latency average times seem to be similar to the regular fpv cams... Also, how heavy is your build, all up and frame weight?

I got the gopro hero session (formerly hero4 session) for 100$ on black friday so it was a no-brainer for me, since I don't need all the fancy features of the hero5. The split is maybe fine, I never tried it, but I think the problems they had with the split 1 kinda makes me feel like this technology is not ready yet. Also, you cannot swap the split from one quad to another easily. I have now 4 working quads and the ability to only have 1 hd camera is pretty sweet.

Yes, I bought the hobbywing combo so I didn't put an ESC entry above since the combo includes both and it would skew the price. The combo has 40A ESC, which is overkill for this build but I love the cleanliness of this stack so much that I put it in all my quads. One note though, I put rubber standoffs in one of these combos between the ESC and FC and ended up ripping off the pin header that connects them in a crash. So now I mount them with nylon standoffs or the provided metal spacers on a screw.

Guides & Reviews

The Rotor Riot CL1 is a community collaborated design based loosely on the popular ImpulseRC Alien and the Martian II. It's a low-budget freestyle frame with thick 5mm x 20mm arms, so it should take quite a beating. Additionally it provides 20mm mounting in the rear for a VTX which is a nice touch. It's very easy to build and perfect for a first build. The parts I chose for this build are a balance..

The EV200D is Eachine's long awaited follow-up to their budget oriented EV100. These offer a much larger 42 degree field of view (FOV) on 16:9 720p LCoS displays. This is the second goggle to utilize the LCoS technology behind the failed Topsky F7X. Traditionally FPV goggles use LCD displays, so LCoS is unproven, but Eachine did a great job implementing the technology.
